The words of the wise are compared to “nails fastened by the masters of assemblies” (Eccl. 12:11, King James Version). The Revised King James Version reads, “as nails well fastened are the words of the masters,” etc. Others (as Plumptre) read, “as nails fastened are the masters of assemblies” (compare Isa. 22:23; Ezra 9:8).
